Title: Improvements in or connected with means for removing feathers, stubs and down from poultry, game-birds, and the like
IPC: A22C21/02
Filed: 1930-07-21
Abstract: 359,439. Plucking poultry. BUDD, A. G. and BARTON, H., Station Garage & Motor Works, West Moors, Wimborne, Dorset. July 21, 1930, Nos. 22003/30 and 2061/31. Addition to 337,379, [Class 28 (ii), Kitchen and like appliances &c.]. [Class 28 (ii).] The machines for plucking poultry described in the parent Specification are provided with means for positively separating the resilient gripping- members to permit the feathers to be plucked to enter between them, the grippers being then released to grip the feathers. The opening means may also serve for clearing the feathers from the grippers, or, separate clearing-means may be used. As shown in Fig. 2, the resilient grippers 1 are mounted on discs 3 on the drum or shaft 4, and have inwardly directed gripping surfaces 9. The discs are shown widely separated in order to illustrate the construction. The grippers are opened to permit the feathers to enter between them, by a disc 5 having a fibre extension 6 which engages between the grippers as they approach the featherengaging position. In order to prevent the extension 6 from contacting with the gripping-surface proper, the surfaces 9 are recessed at 10 and the extension 6 engages only with the recesses. The disc 5 also carries an extension 7 which similarly engages the recesses 10 to open the grippers for clearing the feathers, the clearing being effected by a narrow projection 11. The discs 5, one being provided for each series of grippers, are prevented from rotating by an adjustable stop bar. In Fig. 8, the resilient members 19 are formed on the sides of discs or quadrants 14, which may themselves be flexible. The members 19 may each be secured to its disc at one end by rivets 18, the other end being free to slide. The gripping surfaces are formed on or secured to the adjacent parts of the members 19 leaving a recess to be engaged by the opening members which operate as described with reference to Fig. 2. The grippers 19 may be stepped as shown at 20 to allow the grippers to snap together quickly to engage the feathers. In a modification, the opening members are in the form of a comb, each tooth projecting between a pair of grippers. Fig. 9 shows a vertically-adjustable guard 22 secured over the working opening of the machine casing. The upper edge of the guard is of comblike form to bring the feathers into correct position for gripping by the resilient members. The grippers are preferably arranged in a readily detachable manner and the gripping surfaces may be roughened. A fan or the fan action of the rotor removes the plucked feathers. According to the first Provisional Specification the opening means are secured to the casing of the machine and project inwardly into the path of the grippers.

Patent GB-717802-A (GB)
Title: Improvements relating to the finishing of thermoplastic tubes
Inventor: EVERETT SAMUEL JAMES
IPC: B29C59/00
Filed: 1952-09-02
Abstract: Tubular articles, particularly barrels of hypodermic syringes, of glass or other thermoplastic material, are provided with a matt surface in the bore, and are subsequently brought to the correct bore dimensions by heating on a mandrel, the matt surface being preserved. The matt surface is stated to give better sealing with a piston than a smooth bore.  The bore of a tubular blank is roughened mechanically, e.g. by lapping or sand-blasting, or chemically, the resulting bore diameter permitting the blank to be placed over a mandrel which preferably has a coefficient of expansion greater than the blank.  The heat applied expands the mandrel and blank differentially, the blank being so stretched that when the mandrel and blank are cooled, the latter is of the required bore size and may easily be removed from the mandrel. Alternatively, the blank, when softened by heat, may be pressed on to the mandrel by fluid pressure, such as external air pressure, by internal vacuum or by mechanically rolling the outer surface of the blank whilst the blank and mandrel revolve.  The blank may be formed at one end with a nozzle for the needle, and at the other end with an outwardly directed flange, before the matt surface is produced by lapping.  The stretching of the blank may be effected in stages on two or more mandrels.

Filed: 1926-09-14
Abstract: 258,591. Fondaire, A. Sept. 16, 1925, [Convention date]. Portable checking and recording clocks for races &c.-In apparatus particularly for timing the arrival of pigeons a rectilinearly movable compartmented member carries a recordstrip adapted to be pressed against time type wheels 2 to record the time of each advance of the said member after the reception of a token. The mechanism is enclosed in a bipartite casing and means are provided for perforating the record-strip when the casing is opened. As shown in Figs. 1, and 2 the casing comprises two parts A, B, hinged at 1 the part A enclosing the token receptacle or compartmented member 26 and the impression mechanism and the part B containing the clockwork and time type wheels 2. The receptacle 26 is guided on rods 28 and is advanced passed an insertion slot 27 for the tokens by means of a push rod 29 controlled by a spring 35 and provided with a spring controlled pawl 30 cooperating with teeth 31 on the base of the receptacle; the receptacle is retained in adjusted position by a detent pawl 33 co-operating with a second set of teeth 32 on the receptacle. During the movement of the receptacle a tooth 31 acts upon a bell crank 38, Fig. 7, pivoted on a support 41 and through the projection 51 thereof and a pin 52 on an arm 39 rocks this arm to stress the spring support 44 of the impression pad 46, the arm being connected to a lug 43 on the support 44 by a link 42 having pins engaging slots 47, 50 in the arm and lug respectively. When the bell crank 38 is freed from the tooth 31 the pad 46 forces the record-strip 21 against the time type wheels 2; the record-strip is carried by supports 25 secured to the receptacle 26. The bell crank 38 is controlled by a spring 53 acting upon a pin 54 on the bell crank. The connection between the bell crank 38 and arm 39 prevents operation of the impression pad during the return movement of the receptacle 26. The part A is held in the closed position by two catches 6 thereon engaging two pivoted bolts 7 on the part B. A link 9 connects the bolts and opening of the casing is effected by a pull rod 11, Fig. 2, which carries a plate with a pin 13 engaging a cam portion on one of the bolts so as to release the bolts from the catches. At the same time a second pin 15 on the plate engages a pivoted cam on an arm 16 and thus rocks a shaft 18 to cause a pricker 20 on an arm 17 to perforate the record strip 21. A plurality of records may be produced by an assembly of record-strip with interposed sheets of copying paper.
